“…Despite the vast number of reports on 3D, bulk MOFs, synthesis and characterization of 2D, single layer MOFs are much more limited. [1][2][3] Intrinsic 2D MOFs are expected to attract increasing attention since they are anticipated to possess exotic electronic properties, such as high electrical conductivity, [4][5][6][7][8] superconductivity, [9,10] topologically non-trivial band structure, [11][12][13][14][15][16][17] halfmetallic ferromagnetism, [18][19][20][21] and quantum spin liquids. [22] To isolate their intrinsic electronic properties from the substrate, synthesis of 2D MOFs on inert surfaces, such as graphene, other van der Waals layered materials, and bulk insulators, is highly desired.…”
